SAP modified bitumen roof valley is applied by first ensuring the substrate is clean and dry. The modified bitumen is heated to the appropriate temperature for optimal flow and adhesion. It is then poured or spread into the valley area, ensuring even coverage. The material is typically reinforced with a fiberglass mat for added strength. After application, it is rolled to eliminate air pockets and ensure proper bonding with the existing roofing system, enhancing durability and waterproofing.
